Description
Technical Field
The invention relates to the technical field of material connection processes, in particular to a method for connecting a fiber reinforced thermoplastic composite material and metal.
Background
Fiber Reinforced thermoplastic composites (FRTP for short) have the unique advantages of strong designability, high strength and rigidity, good structural dimensional stability, corrosion resistance, good fatigue fracture resistance, special electromagnetic properties, convenience for large-area integral forming and the like, and are increasingly applied in the fields of aerospace, national defense and military and the like.
For ultrasonic welding of FRTP samples, high energy is required to melt the FRTP surface resins and then wet each other. But since the FRTP surface is not absolutely flat, it is necessary that the melted and softened resin compensate for the gap problem due to parallelism by flowing and deforming. On one hand, the resin content of the surface of the composite material with high fiber content is less, and the distribution of the resin on the FRTP surface is not uniform, so that more welding time is needed, more energy is needed to keep the thickness of a solution layer in a welding seam unchanged, and steady-state melting occurs. More energy input will affect the matrix, heat affected zones and defects (cracks, pores) will appear at the interface, degrading the joint performance. On the other hand, since both are made of different materials and the joint side contains fibers, the difference between the thermophysical properties of both is large, and a large stress is generated at the interface, resulting in stress concentration.
By adopting laser connection, the heat of the laser beam irradiated to the metal side is acted on the interface of the metal and the fiber reinforced thermoplastic composite material through heat conduction, certain heat damage can be caused to the matrix material, the existing time of a molten pool generated by the energy of the laser beam is short, the size is small, the FRTP resin cannot form sufficient flow, and a plurality of small pore defects can be remained on the interface.
Therefore, a method for connecting a fiber reinforced thermoplastic composite material and a metal is needed to solve the above problems.

s01, arranging an intermediate layer made of short fiber thermoplastic composite material between the connecting interface of a first workpiece made of fiber reinforced thermoplastic composite material and a second workpiece made of metal;
s02, applying ultrasonic waves to the side of the first workpiece far away from the middle layer, and applying laser beams to the side of the second workpiece far away from the middle layer;

In the welding process, the arrangement of the middle layer can absorb the energy of the heat conduction of the laser beam, prevent the heat from being directly acted on the first workpiece made of the fiber reinforced thermoplastic composite material and prevent the material matrix of the first workpiece from being thermally damaged, and when the ultrasonic wave acts on the first workpiece made of the fiber reinforced thermoplastic composite material, the middle layer can improve the sound energy density at the connecting interface, increase the heat generation speed and reduce the welding time; on the other hand, in the process of combining the workpiece I and the workpiece II, the laser beam and the ultrasonic wave can be transmitted and concentrated to the middle layer, and the middle layer is heated and melted firstly and flows and spreads towards two sides under the action of pressure. Because the middle layer contains short fibers, the short fibers are remained in the welding seam, the fiber content of the welding joint can be improved, the stress concentration at the connecting interface is reduced, and the welding strength is improved.

Detailed Description
In order to make the technical solutions of the present invention better understood by those skilled in the art, the technical solutions of the present invention are further described below by way of specific embodiments with reference to the accompanying drawings.
In the description of the present invention, it should be noted that the terms "upper", "lower", "left", "right", "vertical", "horizontal", "inner", "outer", and the like indicate orientations or positional relationships based on the orientations or positional relationships shown in the drawings or orientations or positional relationships conventionally laid out when the product is used, and are only for convenience of description of the present invention, and do not indicate or imply that the referred device or element must have a specific orientation, be constructed in a specific orientation, and be operated, and thus, should not be construed as limiting the present invention.
As shown in fig. 1 to 2, the present embodiment provides a method for connecting a fiber reinforced thermoplastic composite material and a metal, comprising the steps of:
s01, disposing an intermediate layer 300 made of a short fiber thermoplastic composite material between the joining interface of the first workpiece 100 made of a fiber reinforced thermoplastic composite material and the second workpiece 200 made of a metal;
s02, applying ultrasonic waves to the side of the first workpiece 100 far away from the intermediate layer 300, and applying laser beams to the side of the second workpiece 200 far away from the intermediate layer 300;
s03, ultrasonic welding and laser beam welding are performed simultaneously.
In the connection method of the fiber reinforced thermoplastic composite material and the metal provided by the embodiment, in the welding process, the intermediate layer 300 is arranged, on one hand, the energy of the heat conduction of the laser beam can be absorbed, the heat is prevented from being directly acted on the workpiece one 100 made of the fiber reinforced thermoplastic composite material, the material matrix of the workpiece one 100 is prevented from being thermally damaged, and when ultrasonic waves are acted on the workpiece one 100 made of the fiber reinforced thermoplastic composite material, the intermediate layer 300 can improve the sound energy density at the connection interface, so that the heat generation speed is increased, and the welding time is reduced; on the other hand, during the bonding of the first workpiece 100 and the second workpiece 200, the laser beam and the ultrasonic wave can be transmitted and concentrated to the intermediate layer 300, and the intermediate layer 300 is first heated and melted under pressure and flows and spreads to both sides. Because the middle layer 300 contains short fibers, the short fibers are remained in the welding seam, the fiber content of the welding joint can be improved, the stress concentration at the connecting interface is reduced, and the welding strength is improved.
As shown in fig. 1, the ultrasonic horn 400 is disposed above the first workpiece 100, and the ultrasonic waves generated by the ultrasonic horn 400 act on the first workpiece 100 made of the fiber-reinforced thermoplastic composite material; the laser beam 500 is arranged below the second workpiece 200, and the laser beam generated by the laser beam 500 acts on the second workpiece 200 made of metal; the intermediate layer 300 is disposed at the joint interface between the first workpiece 100 and the second workpiece 200 to improve the welding strength of the joint interface and reduce the defects such as cracks and air holes.
Preferably, before step S01, the method further includes: and sequentially flattening, cleaning and air-drying the surface of the connecting interface of the first workpiece 100 and the second workpiece 200 by using sand paper. Specifically, fine sand paper is used for smoothing, alcohol is used for cleaning, and the workpiece is naturally dried for later use, so that the welding strength of the first workpiece 100 and the second workpiece 200 is improved.
Of course, in other embodiments, the whole of the first workpiece 100 and the second workpiece 200 may be sanded, cleaned with alcohol, and naturally dried for use.
Preferably, in step S01, the first workpiece 100 and the second workpiece 200 are fixed by a fixture to prevent the first workpiece 100 and the second workpiece 200 from vibrating under the action of the ultrasonic waves and the laser beams to affect the welding strength.
Preferably, in step S03, the moving speed of the laser beam from one end to the other end of the joining interface of the first workpiece 100 and the second workpiece 200 is set according to the welding time of the ultrasonic wave to ensure that the action time of the ultrasonic wave and the action time of the laser beam are the same.
Further, in step S01, the thickness of the intermediate layer 300 is 0.1mm to 0.5 mm.
Preferably, in step S01, the first workpiece 100 is made of a fiber reinforced thermoplastic composite material with fiber layup in a unidirectional mode, i.e., a unidirectional laminated board, and is formed by laminating and pressing unidirectional non-woven fiber prepreg layup sheets along the same direction.
Alternatively, the first workpiece 100 is made of a fiber reinforced thermoplastic composite material with a fiber layering mode of multidirectional layering, namely a multidirectional laminated plate, and is formed by laminating and pressing unidirectional non-woven fiber prepreg layering sheets along a laying mode with the same direction angle and the same layering number along each direction.
Unidirectional plies and multidirectional plies have a high structural stability. During ultrasonic welding, the weld joint interface of work piece one 100 and work piece two 200 is subjected to pressure primarily in the vertical direction. For a workpiece without the energy-guiding ribs, although the resin is heated and melted and flows at the interface, the original distribution state of the carbon fibers is not obviously changed and still is in the original unidirectional or multidirectional layered distribution.
Optionally, in step S01, the second workpiece 200 is made of a non-ferrous metal. The non-ferrous metal has the advantages of excellent performance, corrosion resistance and high strength.
Illustratively, the material of the second workpiece 200 is aluminum alloy or titanium alloy.
In the present embodiment, the size of the first workpiece 100 is 60mm × 20mm × 2mm, the size of the second workpiece 200 is 60mm × 20mm × 2mm, and the length of the connection interface between the first workpiece 100 and the second workpiece 200 is 10 mm.
Preferably, the thickness of the intermediate layer 300 is 0.1mm to 0.5mm, so as to ensure the welding strength of the first workpiece 100 and the second workpiece 200 and reduce welding defects such as cracks, air holes and the like.
Furthermore, the power of the laser beam is 50W-100W, so that the welding strength can be improved while the welding time is reduced.
Preferably, the laser beam is a linear laser beam to laser weld the joining interface of the first workpiece 100 and the second workpiece 200.
The welding process is as follows: the linear laser beam moves from one end of the joining interface of the first workpiece 100 and the second workpiece 200 to the other end, and then the laser beam 500 is turned off to melt the thermoplastic resin in the intermediate layer 300 by thermal conduction. On the other side, the ultrasonic horn 400 contacts the second workpiece 200, applies pressure and starts to vibrate, and the high-frequency vibration friction generates heat to heat the polymer material to the melting point of the polymer material. Under the combined action of the two, the molten resin flows into the joint surface and flows and spreads to both sides. Due to the addition of the ultrasonic waves, the time for melting the resin at the interface between the FRTP substrate of the first workpiece 100 and the intermediate layer 300 is longer, the melted resin can be spread more sufficiently, gaps at the interface are filled, and the generation of air holes is also inhibited. The intermediate layer 300 is then melted in a steady state to form a thin molten layer, intermolecular diffusion occurs at the interface, and a reliable joint is finally formed as the weld cools and solidifies.
According to the method for connecting the fiber reinforced thermoplastic composite material and the metal, the composite material with high fiber content and the metal are automatically, reliably connected with low cost through an ultrasonic-assisted laser connection technology; the intermediate layer 300 is designed and added at the connecting interface, so that the problems of interface stress concentration, a joint heat affected zone, air holes and other defects are solved, and the overall strength of the joint is effectively improved.
It is to be noted that the foregoing is only illustrative of the preferred embodiments of the present invention and the technical principles employed. It will be understood by those skilled in the art that the present invention is not limited to the particular embodiments described herein, but is capable of various obvious changes, rearrangements and substitutions as will now become apparent to those skilled in the art without departing from the scope of the invention.
